I have ~12,000 machines running KES8 and my help desk started getting calls about an hour ago saying users were having problems accessing various web sites. I did all my typical troubleshooting and was not able to find a problem and I was not having the problem on my Linux machine that I use on a daily basis. So I went over to some of my lab Windows XP machines and I was having the same problem. I was able to change a setting and tell KES to stop monitoring port 80 and then I could then access the web sites again. I turned the monitoring of port 80 back on and it broke the browser access again. I can not find any logs as to what is going on. I was able to roll the updates back in KES8 on one machine it the browser was working with port 80 being monitored.... so it seems like a bad update or something that went out.

I've opened a support ticket, but support is normally slow. I thought I would post here. Any ideas???

FYI: My Linux machine does not run AV software, so that's why I did not have the problem there.

I think I was able to fix the problem by turning off monitoring of port 80, 443, and the port we use for proxy which is 8888. I changed the policy on the server and I'm hearing good things.... this is by no means a "FIX". It was a temporary fix at best.

Here is the problem I noticed as well... which is not cool. If a machine is having the problem it can not download updates from either KSC or the internet site. So even if they were to fix the update you're machines are kind of hosed.

Interestingly, it is only affecting our Windows XP machines. On-line chat w/support said average wait was 50 minutes. Telephone support recording said that they were experiencing EXTREMELY high call volumes...

disabling the web antivirus in my workstation policy seems to have allowed user to browse again. Very strange. In my case, only google.com was accessible... not other sites including our sharepoint sites, OWA, msn and pretty much everything else was not available. I'm on hold now with enterprise support... and have been for an hour! lol I'm guessing they're experiencing a higher number of calls.

What a joke... I wish they would just monitoring their forums and maybe It would stop some people from sitting on hold forever. I opened an electronic ticket, but I don't expect a response anytime soon.

I've had success going to the policies (both Workstation and EndPoint) for the Managed Computers container and turning off port monitoring for both port 80 and 443, but Dave's option of turning off Heuristic Analysis would probably be the better way of doing it.

Same problem here. Disabling the Web Anti-Virus component seems to have worked. Windows 7 computers did not experience the problem. I cannot believe that we left AVG for this. Nothing but problems. First a wonderful 50/50 chance of successful install/deployment, then Network Attack Blocker and now this. Wow. I'd rather have the home user version of Kaspersky on our machines here instead of the bloat that is KES. Well done.
